Tasks

H2 Hub nahKRAFT GmbH is planning the construction of a 5 MW electrolysis plant for the production of green hydrogen. The plant is designed to convert electricity from renewable energy sources into hydrogen for cross-sector applications, store it, and supply it on demand – primarily for the mobility sector. In a second construction phase, the plant will be expanded to 15–20 MW.

Project description

INP Deutschland GmbH was ordered as Owner’s Engineer for the technical planning services, covering preliminary design, basic design, and permitting design. A digital twin was used to develop and simulate the total energy concept and for sizing the main components especially storage systems. In addition to the electrolysers, the plant comprises all required auxiliary systems, including cooling systems, water treatment, compression, storage, filling systems, electrical supply, and control systems.
In preliminary and basic design phases, the main and auxiliary systems as well as the associated buildings were planned in detail. For the permitting phase, the required documentation was prepared and submitted as part of the building permit application. A key aspect of the project is the energy concept. Regulatory requirements related to the power supply were assessed and incorporated into the design. Corresponding scenarios were developed and the necessary simulations were carried out. The goal is to prepare a complete engineering design package for a 5 MW plant, which will be approved as part of the building permit application. The plant is designed for a subsequent expansion to 20 MW, subject to approval under the German Federal Immission Control Act (BImSchG).
